If you were to buy a S5 do not buy from a secondary site unless a bargin. You want the 90 day warranty.
Currently they have them on bitmain's site for sell (they temporary said sold out but it now appears to have more stock). Order direct on S5. If older gear then look into secondary markets.
Phils comment of "case of pennywise pound foolish. " is pretty correct. If you try to save a few bucks in this game it will come back to bite you most of the time.
So it's better to order directly on Bitmain's site ? Do they accept credit card ?
I have always used BTC. But they say they offer it through "DHGate store" which currently say's sold out. But their BTC store say's in stock.
This could change sometime yesterday they said they were out of stock, then it came back in stock. So hard to say how many they have.
Here is link to official bitmain site: https://bitmaintech.com/productDetail.htm?pid=00020150303095018716e2uWKIA70662
I've tried to do a checkout and they also offer to pay in USD on Bitmain's site so I think it's ok. But what would be a typical good PSU for the S5 ?
this is 113 you can use paypal. it is on sale
